Final answer:
Bacterial Vaginosis is typically caused by an overgrowth of Gardnerella vaginalis and manifests with symptoms like vaginal discharge and odor. It is distinct from gonorrhea, chlamydia, and syphilis, which are caused by different pathogens.
Step-by-step explanation:
The condition that is normally from an overgrowth of Gardnerella vaginalis is D) Bacterial Vaginosis. Bacterial vaginosis is associated with symptoms such as vaginal discharge, odor, burning, and itching. It differs from sexually transmitted infections like gonorrhea, caused by Neisseria gonorrhoeae, and chlamydia, caused by Chlamydia trachomatis. Gonorrhea can infect the reproductive and urinary tracts, while chlamydia is often asymptomatic but can cause complications if untreated. Syphilis, caused by Treponema pallidum, presents in stages and can lead to serious complications in its tertiary stage.
